noel
Synonym discussion
Sense: noun/1
All four words point to the December festival, but they live in very different registers. 'Christmas' is the neutral, everyday choice — what people say, write in messages, and use in news. 'Yuletide' is archaic and literary; you meet it in old songs, marketing copy aiming at a cosy feel, and historical writing, but never in casual speech. 'Christmastide' is the most formal of the four and carries a religious flavour, properly naming the twelve days that follow Christmas Day in the church calendar. 'Noel' (sometimes written Noël) borrows the French word and now lives almost entirely on greeting cards, mantel decorations, and in song titles such as 'The First Noel'. Compare: 'We are spending Christmas with my parents' (natural), 'Yuletide greetings from our family' (a printed card), 'A blessed Christmastide' (a church bulletin), 'A Joyous Noel' (the front of a card).
Etymology
Borrowed in the late 1300s from Old French 'noel', itself from Latin 'natalis' meaning 'relating to birth' — the same root that gave English 'native' and 'natal'. The Latin phrase 'dies natalis' was used by early Christians for the birthday of Christ, and the noun shortened and travelled into French as 'noël' before crossing into English. The French spelling with the diaeresis on the 'e' (noël) is sometimes preserved in English print, especially on cards and signs.
